How to use the Volumetric Heat Haze option in V-Ray VolumeGrid to achieve a distorted effect

I tested your set-up as well as a new scene with a VDB Pyro Sim. It seems to work as expected with no Freezes appearing. You can see the results of the test here: http://ftp.chaosgroup.com/support/sc...5_09-45-57.mp4

Could you try sharing the VDB as well through our Report System to see if it's what causing the Freeze? https://support.chaos.com/hc/en-us/requests/new

Your test method is wrong, I froze the software when rendering the animation sequence frame, he froze the second animation frame, the first frame is no problem, you can try to render a hot fog of coherent sequence frame, he should freeze the software when rendering the second frame。In addition, during the opening of the interactive process, modifying the hot fog value will also cause freezing, rather than suspending the interactive rendering, modifying the value and then starting the interactive rendering

I was able to reproduce this issue. It is escalated to our Dev Team for further inspection and resolution (VC4D-1999). We will get back to you if we have any updates.

Thank you for your understanding.
